The pH-meter was fresh out of the box and I used it straight away. Didn't calibrate it before. You think it could give so erroneous readings that I should calibrate it before I test?

I hear you, @dwhite60! To those that may be interested; @IslandLizard Just measured the pH in this beer. pH = 2.4 Well below pH = 4-5 (the range it should be).

Thank you, @IslandLizard. I agree that the picture will be more complicated when there are various other components than water in the fermenter. A lot of uncertainties.. I have planned for preparing a new brewing batch upcoming monday/tuesday. Will let the current batch rest in bottles for...

@IslandLizard - got some results for you. I remember I had two small dashes of StarSan/Sure San in the fermenter. When I poured did it in a laboratory flask now, they measured 20 ml each, summing to 40 ml. Smeared it around in the fermenter as last time and left it on the side to gather up...

I like the idea, but up till now many of us have considered that any amount of concentrated StarSan should be regarded as "unsafe" if mixed with the wort. Independent of what I would get as an answer, would it help me in any way to know if it is safe or not? What would be considered as safe? I...

Recipe OG = 1.059 OG = 1.053 Recipe FG = 1.011 FG = 1.005 So in the end, no change in ABV. Used hops in pellets. Tasted a small cup on Tuesday. Opened a bottle now and tasted some more. To me, it doesn't taste bad. Perhaps somewhat more sour than what I am used to for an IPA. My first thought...

Yes, I agree. That is the question I would like to find an answer to. Also read somewhere in the forum about the person drinking some of the diluted StarSan to prove a point. The fact that the fermentation actually went better than expected, given ABV=6.3% (as in recipe) with too small OG...

Thanks. Appreciate both sides to this. If I was Five Star I would also make sure to be on the safe side. If employed in Five Star and a random guy came to me and said he had used it in concentrated form and I would have no chance to control or check that he actually did not use more of it than...

Sorry, link: Polyprotic Acids and Bases in Cola Drinks.

Yes, thanks. Will fix my location. Will also get rid of that sanitizer that I have and get a new one.

According to this the percentage of phosphoric acid is around 0.26-0.3 % in a coke. Data sheet of StarSan gives 50 % concentration of Ph.acid in further an aqeous solution of 75%. Lets say I put 50 ml of StarSan in the bucket with 30 L of wort. Assuming density of StarSan = density of wort...

Actually looks more like this. This is the bottle type I have. Norwegian producer as an alternative to StarSan. Contains both dodecylbenzenesulphonic acid and phosphoric acid. This might well be what I got. 15-40 ml per 10 L water. I could check with the guy I bought it from if this is the one...

I definately There is a label on the bottle, but it has been "whitened out", probably from wear. I have good reason to believe it is the original bottle. However yes, many probably and maybes here. The right thing is to get rid of this stuff and prepare a new batch. Thanks.

From my understanding of it, the fermentation actually went well. I had missed around -6pts in OG, but with the Final Gravity I reached ABV=6.3% which was indicated in the recipe.

Bought the equipment used from an experienced person in home brewing. I asked him and took his word that it is StarSan. Of course, it is not good to only take his word for it..
